I am using a Canon HF100 HD Camera for low level aerial breaking news for our local NBC station and we, several times a week go out and get footage from various locations around the area...... They are using the footage we give them in clips for the news, but..... NBC also is posting the RAW footage on there news page (compressed) for all to see, no problem but Obviously there are times (descending, repositioning etc...) that the footage is not good at all. so, the question......
AVCHD format with a .MTS extension. Is it possible to edit the footage and save it back as a .MTS file with out compressing it? I am currently using Vegas 8.0 Platinum.

Brett,

The answer is yes. I own and use all of the AVCHD editing programs on the market, but the ONLY one I have found which will directly accept raw ,mts files from the camcorder (in my case also an HF100), then allow you to cut-edit and/or append clips together, followed by saving a new output .mts file without any recompression is Nero Vision 5, the video editing program included in Nero Ultimate 8 from Ahead software.

Don't be fooled by the low cost or lack of features which initially make this program appear weak compared to Vegas 8 Pro, Final Cut HD, or other high-end programs, which I also own and use.

This program does some things amazingly well, and what you are asking for is one of them.

I suggest you check it out, and be sure to enlarge the editing screen to fill your monitor since the program opens with a small and uninviting work space. You will find the output file as I described in the STREAMS folder in the BDMV folder you create on the hard disk at output time. As you probably already know, this is the same location the file(s) initially were stored in the camcorder recording.


Please report back on your results. The free trial of the program should allow you to try it with no risk, but it is a no-brainer purchase IMHO for $60 or $70 bucks.

This is an almost total lack of knoledge of this program by most if not almost all AVCHD users, and this is mostly due to ignorance and a lack of marketing by the software developer. It also makes outstanding AVCHD disks which play extremely well on my BluRay players here, something which is not true for several other programs claimed to be AVCHD-ready.........and which cost a great deal more.

Hope this helps,


Larry

Larry,

Are you able to copy the Nero Vision 5 edited .MTS file structure back to an SDHC media card and have it playback in the HF100?

Awesome I will try it now!
I will let you know if it does what I want!
Thanks

Nero 8.0 is what I have found.....Seems to include Vision 5?
I assume this is just the newer version.
I am downloading it currently, so I will know something shortly.
Again thanks!

It will work just fine Brett. I have been doing this with AVCHD since Nero 8 came out last year but the newest version of Nero Vision 5 is by far the smoothest and best version to use..

Bruce,
With the small caveat that I have only tried the simpler examples of what you ask for, I can happily report that Nero Vision does indeed write a BDMV folder which not only plays back properly on the HF100, but actually forces the HF100 to generate a new set of thumbnails in the "AVCHDTN" folder it keeps. I have not tried a lot of editing, and only have used the simplest examples with non-rerendered content of the original clips, so please don't construe this to mean that all edited .mts output from Nero will play in the HF100 after editing. While this may be true, I simply have not tried it, and frankly have had no reason to try it. I will also note that very few other AVCHD programs generate .mts file output, and most produce .m2ts files which a BluRay player knows how to handle. Nero creates exactkly the same file output type as it gets from the camcorder as input, .mts.

Hope this answers your question.

Larry

Bruce,

I did one more experiment based on your prior question, to see if the HF100 could play back a heavily edited series of clips which Nero Vision produced. I took 4 clips totally about 12 minutes in length, applied several color corrections and filters, sharpening, several 3-D transitions, a few titles here and there, and then rendered the output creating a new BDMV folder. This was then used to entirely replace the original BDMV folder on the SD card, leaving all the other SD card content intact.

The HF100 plays back the entire video beautifully, with all of the editing and re-compression, causing no issues whatsoever. I had expected that maybe some glitches, stuttering, or possibly a hang or crash could occur, since I would not expect the camera to have a particularly exhaustive or robust error processing capability. Thankfully and much to the credit of the Nero software folks, the edited output played exactly as it should.

So my final conclusion would be that this program, unlike any other I am aware of, can and will not only write .mts files as output, but can allow a complete "copy back to the camera", at least in the case of the HF100, albeit with manual file copy required to the card.

This just adds to my original contention that this piece of software is a true gem.

Hope you find this helpful and interesting.

Best,


Larry

Do you know if Nero works with Vista Home Premium 64 bit system?
Also how will it work with a sony sr12.

Quad core q6600 @ 2.4Ghz.

Can't find Vision 5!!
Everytime I click on a download link it takes me to Nero 8.

Nero Vision is included in Nero 8

OK,
Got the full program....
Please excuse my lake of knowledge of video editing with this next question.....
How are you exporting the finalized "movie" to be assured the output file is the same as the input file? In my case .mts?
I have exported a small clip and it created a .mp4 file?

Brett,
1. Open Nero Vision.

2. Choose Make DVD>AVCHD

3. Choose Add Video Files

4. Navigate to where your camera clips are located, usually in the STREAMS folder in the BDMV folder on your camera SD card. Select and load the .mts clips you want to edit.

5. Resize the window to fill you screen, to make it easier to see and edit.

6. Use the buttons on the left to Move Up, Move Down, Merge, and edit the clips, thus trimming, rearranging, and appending them together as desired.

7. Optionally apply video effects, text effects (titles) and / or transitions to the clips (but remember that any of these optional steps will force recompression to occur)

8. Hit the Next button in the lower right corner to move to the Menu design page.

9. Choose Do Not Create a Menu.

10. Again hit the Next button in the lower right.
If you want to preview the edited clips, use the remote control buttons to simulate playing the AVCHD disk. Otherwise, skip this step by hitting Next once again in the lower right corner.

11. On this burn page, note that it displays the Smart Rendering status for each of the clips you originally selected. The clips which had no added filters, effects, titles, or transitions should show up in the list as 100% Smart Rendered. If you optionally added filters, text, transitions, or titles, you will see lower percentage numbers for these affected clips. If you, for example, did color correction on only half the clip, then the other half will still remain Smart Rendered at 50%.

12. At the top right corner of the page, choose Burn to Hard Disk Folder and select Desktop, where the output AVCHD folder will be written.
Hit the Write button in the lower right corner and the output process will commence, showing you the very rapid creation of the output, For non re-rendered content which, as Brett desires, has only trimmed and spliced content but no new titles, effects, etc., the output will be extremely fast, maybe 2 or 3 minutes total.

13. When this burn / output ends in a couple minutes, you will find on your Desktop an AVCHD folder containing a BDMV folder containing a STREAMS folder containing the new .mts files, exactly the same quality as the originals but trimmed, spliced, etc. in the manner you chose.

Optionally move this BDMV folder onto your SD card replacing the original folder if you want to view the results on your camera, or play it on your computer screen using the Nero program ShowTime.

For Brett's specific application, copy the .mts files to your NBC website as you would any other .mts content.

Hope this makes the process clear. I am here to assist if you need further help.

Hi Tom,
Thanks and it is my pleasure to help out. I am not familiar with the 64 bit Vista compatability but suggest you check the Nero website. I have used Nero with several AVCHD camcorders, and it seems to handle them all the same way as I described for my Canon HF100. I have NOT tried your specific camcorder though, and suggest you download the trial and see for yourself. I'm guessing it works fine, but please let us know.


Larry

You are awesome!!!!
Thanks for the info

Tom,
Just for your info:
The trail version would not process AVCHD info, well not totally true, it would process the audio but not the video.
I had to purchase the full version for it to work properly.

I guess I am not entirely surprised that Nero forces you to buy the real software in order to get full AVCHD support, since the mpeg4/h.264 licensing fee is levied on them with any functioning h.264 program they distribute, trial or actual. As you will soon find out, you are getting your money's worth with this 11 program product. Their ShowTime player does full BluRay, AVCHD, and HD DVD playback, including raw .mts, .evo, and other special formats. Their audio editing program SoundWave Editor has great Digital Dolby support and closely resembles Sony's $299 Sound Forge. Their Nero Burning software is the best in the industry for burning disks IMHO, and their Nero Vision program is a true gem, as I have already stated. There are another 7 programs in the package which do all sorts of other useful things. At $60 bucks or so this is an extraordinary package, and little appreciated for AVCHD and BluRay. Their customer support is really bad, however, as it is, unfortunately, for many of the other video editing programs, both expensive and cheap.

Please report back on your progress Brett.....

Larry;
This is the reply I got from Nero when I asked if Nero8 was able to work with Vista 64 bit edition.

Dear Mr. "Tom O'Farrell",
Thank you for your e-mail and your interest in our software.
Nero 8 is compatible with Vista 64.
If you have any further questions please do not hesitate to contact us.

Best Regards

However Sony "Picture Motion Browser" (congrats to the commitee that named this program) is not compatible with 64 bit. The SR11/SR12 operating guide states this, (page 26 at bottom right) so I must find a way of getting the SR12 HDD content into either a folder in the computer as files that Nero can open and work with, or preferably directly into Nero itself. Unless my memory is playing tricks on me did I not read you telling us that we can by-pass the Sony software and indeed can use Nero to import directly? If so then all is solved for me, I think (being an optimist). Does Nero also have camera control ?

Tom O'Farrell.

Nero Vision does provide capture / ingest from camcorders as well as capture control and also scene detection, but this is not likely to be universally compatible with all camcorders based on my experience with many of the programs and camcorders I have used and tried. I have never personally used Nero's capture features, so I am not really sure whether it even works at all with my own camcorder, the Canon HF100, or with your Sony.

2 immediate thoughts Tom:

Use the SR12 memory stick option and a reader to avoid the Sony software incompatibility

Or

Try Nero trial to see if it can capture from the SR12

Either approach may help solve the problem.

I've read about many others that have successfully run PMB on Vista 64. Yes, Sony doesn't support it, but it does work.

What kind of computers are you guys using with Nero Vision? I don't think it has smart proxy (like videostudio), so I'm not sure if my AMD dual core 5400+ can work with it. As was mentioned, the trial version does not allow you to edit AVCHD, or else I would test it. I am finding stutters during cuts (even without transitions) in my videostudio projects that hopefully won't exist in Nero. Thanks.

I'm running the 64 bit Vista and PMB works fine for me. I've read about many others that have successfully run PMB on Vista 64. Yes, Sony doesn't support it, but it does work.

Me too, haven't had any problems with it except one which I just found a fix for, and it's not tied to Vista 64. While browsing around the Sony site looking for this fix, I noticed some support postings about Vista 64 installer updates for PMB.

I came to these forums to leave this tip behind somewhere. PMB 3.3.x.x has two playback modes - performance priority and function priority. When you upgrade, it apparently switches from the former to the latter automatically. I had some CX12 AVCHD files that I couldn't play through PMB once they were edited with Corel Pro X2 software. Sometimes I was just chopping a few minutes out of the video. Some of these would play if I switched from "video playback mode" to "slide playback mode".

The symptom was that I'd click to play the video, it would bring up the playback screen, and just hang there as if it was trying to pull in the file.

I found this stray reference to a PMB Performance Switcher. I just downloaded it and switched to performance mode, and all the videos (edited or not) now seem to play fine.

Here's the link:

Larry,
Thanks for the information. Nero Vision can do exactly what I’ve been looking for: to split and save .mts files (produced by Canon HG10) without recompression – or with minimum recompression.
But what do you think are the ideal settings to maintain the results the CLOSEST AS POSSIBLE of the original files?
Usually I use the standard settings (on “video options”, before writing the files):
Video mode: NTSC
Nero SmartEncoding: Automatic
Video format (MPEG-4) / encoder / quality setting: Normal
Quality setting: Automatic (fit to disc)
Sample format: Automatic
Encoding mode: Fast Encoding (1-Pass)
It’s a strange thing to me, but changing the settings to "high" produces smaller files with lower bit rates. It should not happen the other way around - produce larger files with higher bit rates?
I tried saving a small file with all possible options and the results were these (audio always on “automatic”, no editing except cutting):
1) Normal settings [as above]: File size: 47.1 MB, Overall bit rate: 15.4 Mbps
2) Encoder on “highest”: File size: 46.2 MB, Overall bit rate: 15.2 Mbps
3) Encoder and quality settings on “high” / “highest”: File size: 41.6 MiB, Overall bit rate: 13.6 Mbps
4) Encoder and quality settings on “high” / “highest”, mode 2-pass: File size: 41.6 MiB, Overall bit rate: 13.6 Mbps

Thanks.

Silvio,

When Nero Vision is used with its default settings, the output file is not recompressed, and the file retains the original quality completely. The output file is written as a copy of the original clips with the same GOPs, the same bit rates for video and audio, etc. There is no better setting.

This exact copy will only occur if the original clips are being trimmed in length, are being used with no trimming, and / or are being spliced together.

Once any other changes take place, then recompression is required, since new frames have to be created. Therefore, any change such as adding titles, transitions, filters, color changes, etc. will cause recompression and lower the quality, sometimes in a noticeable way. The recompression process will also add a lot of additional processing time.

If no recompression is required, the output file is written almost as fast as a pure file copy. For a recompressed video, the time (on my system) increases by a factor of roughly 9X.

There is no confusion as to whether recompression is taking place or not, since the speed difference is very obvious.

I hope I have answered your question, Silvio.

Larry

By the way, my daughter lived and worked for nearly 3 years in Rio de Janiero, and has brought back many wonderful stories and photos of your beautiful country and fine people.

Yes, it was exactly what I wanted to know. Now I’m really enjoying Nero Vision, although sometimes it doesn’t work when dealing with large files and/or various cuts. In these cases, it’s possible to save the changes in more than one step, so it’s not a big problem. And, to simply join the files, MTS_FileJoiner still seems unbeatable.

Obrigado!

Silvio

I have not had the large file problem you describe Silvio.

Nero Vision does smart rendering especially quickly and well. If you do decide you want to add titles, do clor correction, and make any other changes qhich require re-rendering, the output .mts file will also still play properly in the Canon HF100. Therefore, a person could carry the HF100 with edited footage to another location and use the HF100 as a full 1080p HD playback device for the fully edited program.

I have not found any other program so far which the Canon camcorder will accept and playback this way.

Hi Larry. I want to import multiple clips from my HF100 into Nero Vision, trim them and rearrange them on the timeline (no titles or color changes or transitions are necessary), then create a single MTS file (not multiple MTS files), which I can put back onto my HF100 to play. From what you say, it sounds like I can do this with no quality loss, but I can't figure out how to accomplish the editing step. Post #2989 from this link The "Official" Canon Vixia HF10 / HF100 Owner's Thread - Page 100 - AVS Forum (http://www.avsforum.com/avs-vb/showthread.php?t=1014305&page=100) describes one method, but it seems very unusual and painful.

The method I follow produces multiple MTS files, but I want a single movie composed of multiple clips/scenes. Here is what I do:
1) Choose burn AVCHD in Nero.
2) Add files from flash card.
3) Right Click and select edit and trim each file in the editor.
4) Rearrange clips in the order I want.
5) Burn an AVCHD "disk" to my desktop. (This results in multiple MTS files, which I don't want).
6) Replace the AVCHD folder on my Canon flash card with the one created by Nero.

Do you have a different method? Can you describe your workflow step by step? Thanks, as always, for your help.

Larry. Is there any way to divide the scenes from captured tape footage in Nero. When I download the tape footage from an FX7, Nero loads it all into one file. That makes it a bear to edit each scene (trimming, etc.). Pinnacle, for instance, will automatically break the tape into seperate files for each scene, making editing much simpler.

I like the final picture produced by Nero, but as I have stated before, it is not as user friendly as Pinnacle, nor does it have the variety of features. In fact, its Title selection is corny, as is the fact that with most titles, you cannot adjust where they appear on the screen. I am sure there is much yet that I have not learned about the program, but so far I am hoping for a better, user friendly program in the near future, which combines the picture quality of Nero and the ease of use of Pinnacle.

Just airing my frustration.

Peter,
Between your steps 4 and 5 use the Merge button (which I have circled with a pink ellipse in the attached screen shot) to merge the clips into one contiguous file. The output STREAM folder will then only contain a single, merged file as you desire. I have not used / tried this method personally but it does create a single, merged, non-re-rendered .mts output file which should work as you request.

Mike,

I have never used Nero Vision for my earlier HDV editing, but if I were trying to solve the problem you are stating I would:

Use an HDV capture program like HDVSplit (freeware) to capture the HDV content with scene detection enabled. This way each scene change would create a separate clip.

Then, import each clip into Nero and do what you want.

This should overcome the lack of auto scene detection in Nero.

Incidentally, I am not advocating Nero Vision as the ultimate editor, a particularly good HDV editor, or even suggesting it is particularly good for general purpose work. Much to the contrary, I specifically recommnded it in this thread because it can make completely edited files which are then exportable back to the HF100 which the HF100 seems to play absolutely the same as if they had been recorded originally.

This 'export back to the camcorder as an .mts file' feature is sadly missing in all of the other NLEs I use (including Vegas, Final Cut, Pinnacle, etc.), and was specifically requested in the original poster's question. Nero is the only way I am aware of for doing this.

Thanks, Larry. That did work.

I am still unable to get the quality I get using Pixela by using Nero. I have tried many combinations of video options, but, no matter what I choose, once I trim a video in Nero, I lose quality. (If I don't trim a video, Nero produces perfect quality, even if I combine multiple videos (that were edited in Pixela) into one AVCHD disk). I also notice that I never get 100% smart rendering of video once I trim a clip.

Here are options I have used that don't seem to give me good quality:
Video Mode: NTSC
Nero Smart Encoding: Enable
MPEG4 AVC settings: Normal and Highest Quality
Quality Setting: High Quality and Custom
Sample Format: Automatic or Custom
Bit Rate: (when choosing custom) 17,000 kbit/s
Resolution: 1920/1080
Encoding Mode: 1 Pass and 2 Pass
Audio Format: Automatic

Can you tell me exactly what your settings are to get perfect HF100 AVCHD video after editing/trimming? Thanks.

Hello Peter - I have tried the same combinations as you and come up with the same results.
Nero "smart renders" if you are simply combining untouched clips together.
If you do even a basic cut or trim on a single clip - Nero transcodes.

No response yet from Nero tech support as to why. I am still looking for a tool that will allow me to do basic cut edits on the AVCHD files without going thru the transcoding process.

Please let me know if you have found any AVCHD editing tools that will do that.

Corel VS11.5 or higher, it will smart render over jump cuts. It will also do its best to smart render the parts of clips outside its transition effects. But sometimes at the end of transition effects, it glitches when switching back to smart render. A fix is awaited!

Hi Mike. Unfortunately there is a well-documented issue with VS11.5 and VSX2 Pro at least for the HF100. They create stutters before and after ALL cuts/trims of ALL clips. This can be difficult to notice unless you're looking for it or if you have a smooth pan. Sometimes the jerkiness of handheld footage masks the problem. Many people have verified this happens even without transitions or other fancy edits.

Ah. Yes, I see this is referred to on the Corel forum, with no fix yet, though there do seem suggestions it is in XS rather than 11.5. I haven't noticed this issue on my HG10 or SD1 output with 11.5+.
It's not associated with the silly problem they have where the input clips are all UFF but their default o/p is always LFF unless you change it, is it?! They seem to get fields a bit confused here and there...

Hi Mike, I have noticed the stutters on 11.5+ as well. If you do a very slow horizontal pan, and then splice/trim it with VS, you will see stutters before and after the splice/trim. However, I doubt you'd see these stutters on still shots or with hand held footage.
