Can't read the rendered m2t files with VLC...
 

How come i can't render the HDV 108050i rendered files with VLC?
I can read em with WMP but it show the videos cropped in 4/3. :(

Which version of VLC are you using? Also, post a sample file. I have no trouble reading rendering 1080i60 m2t files with VLC for the last two years.

Have you set the preferences in VLC properly?

You don't say what format they're rendered in - apparently, cineform codec doesn't play with VLC

Cineform

Please post a small portion of your rendered .m2t file so we can try it out.

Yep Cineform;that's why!
So wich custom render should i set to read my hdv 108050i?

I want to know which format should i set to have the maximum quality HDV render( so every xp pc could read it).
Thx


have a nice week end

If you're not concerned with Macintosh or Linux viewers, Windows Media Video is very, very good in several ways.

Great codec performance for the bitrate, good rescaling in the player, multibitrate files, good on and off the internet, good automatic codec updates, good penetration with PCs - I'm sure there are some others. Try WMV 9 at perhaps 6Mbps for 1080i.

If you have some control over the PCs that you want to distribute to, Cineform Neo Player is also very good for Cineform codec AVIs, but internet distribution is tough. Do I remember about 28Mbps at medium and 40Mbps at high quality? But great for harddrive playback.

For something that is truely cross-platform/cross-browser, Flash is an excellent choice that Vegas does not handle natively. There are 3 codecs in use - Spark, which is free and greedy for bitrate; VP6 is pretty good, costs several hundred $ USD, but comes with Flash CS3 and Flash CS4; and h.264, great codec, which Vegas can do, but not all viewers can yet handle.

Ok Seth,thanks a lot!
Listen but what should you choose on the template tools to have the best quality HD rendered video?
I wanted also to know what does"uncompessed default" stands for on the Template tools.
Thx

I forgot to tell u that WMP plays the hdv video in 4:3 aspect ratio.Suggestions?

There is no "best" format. Even uncompressed is not best in all circumstances. It may have no compression artifacts, but now you have a huge file that is difficult to move between PCs, that won't play back off a CD, that may drop frames off harddrive playback, etc. What we are looking for is "good" for our current distribution.

Uncompressed is used primarily as a digital intermediate format when moving video between vegas and another application, either because we need all that quality and/or we need to preserve an alpha (transparency) channel.

Uncompressed is not a distribution format - even movie theaters that are doing digital projection on large screens are not receiving uncompressed files, they use a JPEG2000-based compression...

For Windows Media 9, try the 8Mbps HD 1080-30p template or the 6 Mbps HD 720-30p template, depending.

That will be related to pixel aspect ratio. That should be 1.3333 for HDV 1080, or 1.0 for HDV 720p. See it in File | Render As | Windows Media Video 9 | Custom | Video | Pixel Aspect Ratio. If you start with one of the above templates it should be correctly set.

Excuse me ,talking about Pal settings?
"For Windows Media 9, try the 8Mbps HD 1080-30p template or the 6 Mbps HD 720-30p template, depending. "
ican't find the solution hd1080-25

Marcus, after selecting WMV as the file type, click in the Template box and you'll see 5 Mbps HD 720-25p Video and 6.7 Mbps HD 1080-25p Video options.
Select either of these, click Custom, click in the Template box at the top of the Project tab and you'll see even more options.

Thank you,really appreciate your suggestions guys!

Guys just finished to render with the setting WMP9......It is a file of500 kb,how is it possible?
a 11 minutes video rendered in 2 hours and 23 minutes!I think something is wrong.
The same video rendered in cineform:20 minutes.

My pc: 4gb Ram,Nvidia quadro fx 3700,extreme x9000.

I'm not at my computer but do you want to render to an HDV file? That would be an .m2t file extension. In Vegas if you render to a 1080 50i .avi file then its a cineform file.

If you want a HDV/.m2t file you must choose to render with the (i think) mainconcept mpeg2 template. It will give you the option of a rendering to a HDV/.m2t file.

To me it's important to have the loseless quality render in HD,for this reason i'm asking you the templates to choose to have the final HDV.
Unfortunately HDV 108050i cineform can't be read properly by WMP(it appears in 4:3) then Vlc doesn't even open it.I just wanted to join the HDV on my pc.

thx

file > render > Save as: MainConcept MPEG-2 (*.mpg) Template: HDV 1080 50i.

It will save as an HDV file, vlc and wmp can play them.

Will there be a lot of lost in quality with the mpg2?
thx a lot, i really appreciate your infos

No, there shouldn't be a lot of loss. Hopefully it will be unnoticeable. But keep in mind when you copy a copy (unless it uncompressed video/audio) there will always be generation loss.

But if all you do is edit your original HDV files then make ONE render, you should be ok.

Marcus,

What you have to realise here is the difference between an intermediate (for editing) format [such as the cineform .avi] and a delivery (for viewing) format [such as .mpg, .wmv, etc.].

An intermediate format is used to minimise loss due to multiple renders/effects etc. during the editing process. The file sizes will be much bigger.

A delivery format is what you do your final render to, for the format of your delivery medium [DVD, BluRay, WMV, JPEG2000, etc.]. Your delivery medium will determine your maximum permitted file size - and therefore, your final available "quality". For a DVD your final project is limited to around 3.9GB, on BluRay about 23GB - you do the math.

So, it's important not to get apples and oranges mixed up and thereby totally confusing the issue.

Your intermediate files maybe 200GB - clearly that won't fit onto any of the standard delivery media, so, inevitably, you end up having to compress it (a lot) to make it fit. The amount of "lossness" depends in some part to the quality of the codecs used for the compression during the rendering process (the rendering will take longer the greater the compression, generally) and in some part to your viewing medium. Clearly, you won't see much difference between standard DV and Bluray if you're only viewing it on a standard resolution screen. On the other hand, if it's being projected onto a cinema screen, you'll be wanting something considerably more than Bluray's 25MB/s.

It all comes down to "horses for courses".

Hey Steve, thank you for taking the time 4 this good explanation.I really appreciate that!
The problem 4 me began when i was rendering this file and i couldn't play it on my pc!
So i was choosing the avi(cineform) with the template hdv 108050i(pal) then i was asking in the forum how come VLC couldn't read it!Now i got it,i had to render in mpg2 so my full hd monitor could easily show it(WOW!).
So from what i understand if i have to watch this kind of file on a big screen like a cinema i should render in aVi ,is it right(the least loss of quality) or i will have to transfer in a film,am i right?just 4 example

The mpg2 has a really good quality as stated on this thread and i wanna thank you guys 4 the suggestions!

If i m missing anything,please tell me!And once again sorry 4 my english


P.s: i ve rendered 12 minutes of hdv files with music and cc in 13'25 seconds.Final format mpg2 HDV108050i.Is it a good rendering time ?I was about to post in another thread(already opened) but i didn't want to Crosspost!

:)
MM

I tried to make it as simple as I could :-)
Yes, As you have discovered, because VLC is an OpenFormat player, they use OpenSource codecs where possible - hence the Cineform codec is not available to them unless they pay cineform vast amounts of money for the privilege, I guess ;-)
I guess it kind of depends on the size of the cinema screen but, if you're thinking about your local Odeon, they would probably be looking at JPEG2000 - which you'll only get from "REAL" Pro gear. However, raw .avi would probably be the best you could get from Vegas on a standard PC from your original "footage" and would most likely look amazing on a "Home Cinema" projection setup.

:-) Steve

Steve i have no words to thank you bro!Really appreciate it!

What about the rendering times of my pc?Do you thinnk are good times?

I have also an issue on the hdv capture but i will open another post cause i don't wanna change the discussion here!

Thank you bro

It's a pleasure to help where I can

That's always a tricky one to answer, due to there being so many variables involved - effects/rollovers/fades/chroma keying/balancing etc. but that time sounds feasible to me.

I'll keep an eye out for the other thread, although I may or may not be able to help on that subject - depending what the issue is.
