Downconverting
Thanks Nate! Totally agree, so far I only tried the FCP timeline method, suggested by the FCP manual (with horrific results.) Just got my JVC baby 2 weeks ago and so far only shot tests.
Has anyone tried using the AIC (Apple Intermediary Codec) for capture and editing and then doing a downconvert using #3, the "uncompressed 10 bit compressor method (which seem to make the most sense, though for large shows it would chew up space like crazy)? How did it look? I'm trying to shoot a music vid in HDV 720/ 30P but will need to put it on an SD DVD and am trying to come up with the best method. On that note, how about going straight to MPEG2 compression with compessor for the DVD files instead of the 10 bit uncompressed intermediary stage? Has anyone done that? |

For approval DVDs on a short music video project, I'd encode from the timeline. That what I was sending Warner Bros on Static...was cutting in AIC, monitoring in HD externally, and then making SD MPEGS (@23.98!) via Compressor.

What's the value of capturing with AIC versus native HDV 30? I don't believe the AIC has more than a rudimentary capture interface.

HDVXDV -> .m2t file -> Streamclip -> Anything!
I am far from being an expert on this topic.
However, I use HDVXDV for log and capture of 720 24p footage from the HD100U or BRHD50 Deck. The result are .m2t files. I then use Streamclip (It's Free!) (http://www.squared5.com/) I open my .m2t file in Streamclip. I goto Edit -> Fix Timecode Breaks. This is a critical step that HDVXDV does not do and the reason audio gets out of sync using HDVXDV for conversion. I goto File -> Export To Quicktime For Compression Select :Apple DVCPRO HD 720p Quality 100% Make sure: Interlaced Scaling & Reinterlaced Chroma are NOT CHECKED. Enter: 24 into the frame rate box/field. Make sure 1280x720 (HDTV 720p) is selected/. Then select make movie. I then make sure my FCP settings are DVCPRO HD 720 24p in easy setup menu. Import that clips in and can do a great multicam HD edit. Streamclip does beautiful downconversions to SD/DV/DVCPRO. Is there a more efficent method out there? So, please do some experiments and any further feedback on this would be great. Hope this helped someone out there. |

Hey Nate.
Great stuff as usual, very useful to know the difference in quality with all the different conversion methods. BTW, I found the "Uncompressed 10-bit" codec in Windows version too (http://www.blackmagicdesign.com) and it's great if you need to exchange clips between Mac and Windows. Nate, I replied to your email of the 18th, I don't know if you saw it, maybe it got trapped by the anti-spam filter? Thanks again. |

I just read this about the methods for down conversion of JVC HDV footage - (topic save)
I am cutting a show that is in a HDV timeline in FCPro 2. Yet some of my footage is NTSC stock archives in 4:3. The show will be delivered in 4:3 letter box NTSC. So, I am left with a dilemma. How do I down convert all the HDV footage, yet retain the full quality of the NTSC archives? Going out to compressor will result in a long clip with no way for me to replace the NTSC content shot by shot when placed in the NTSC sequence. My plan is to copy paste the show into an NTSC uncompressed 10-bit sequence and then replace all the NTSC archives at 100% scale with letter box crops. But from what I read this method will result in poor down conversion of the HDV. Is there any way to media manage the sequence so all the HDV is rendered to uncompressed 10-bit letterbox clips? |

I ended up down converting the HDV footage to 10-bit uncompressed within FCPro. The results are superb. (gasp) But I used Media Manager to recompress the sequence to 10-bit. By using the Custom sequence settings in Media Manager you do have some control over the recompress, but no filters like Compressor. OTOH, you can continue to edit the shots. I had an hour long doc here. Plus I was able to delete the rest of the material not used.
The downconverted recompressed letterbox looks great and I eliminated the terrible aliasing and flickering in the details of the HDV footage when using a FCPro sequence downconvert. Looks much more film like. This show will get a national audience so, we'll see how people react. Lot's of beautiful footage from Italy and Poland. All shot 720p30 to Firestore as HDV. Edited natively in HDV to fine cut then recompressed to NTSC for mastering to Digibeta. Dave Beaty |

just came to same conclusions as you did. however that doesn't mean i'm happy with the results. I'm ready to download the trial version of adobe suite and give it a watermarked whirl. I've seen good things from adobe premier and dvd burning lately... but to be fair, I havn't checked out FCS 2 yet. For me, it just looks way too compressed and artifacti. yes, compressor, 2 pass best.. 6,7 and 7,7 bit max etc.. nothing close to a store bought DVD, and I think we should be able to get close the quality of one... not obviously home done.
