I-Frame Export for hd2sd
Before I post details of my question, let me ask a simple one that may make my question irrelevant:
Is HD2SD still necessary? (and Jeff Bellune’s process https://bellunevideo.com/tutvideo.php?tutid=12) Or has Adobe improved enough so that I can just render MPEG2-DVD files from Premiere and use them in Encore? I’m using the CS6 versions of Premiere and Encore.
If Adobe is good enough, then I’ll just use that. If not, here is my question:
When I export MPEG2 I-Frame from Premiere, I’m getting frame rate results I don’t understand. My footage is 1080p Canon DSLR stuff at 23.976 fps. I’m trying to get an MPEG2 I-Frame that matches the source. These are my export settings:
And the bottom part of the settings…
But the final video, which I expect will be 23.976 fps shows 29 fps in the properties info:
Why doesn’t it say the expected 23.976 frame rate in the properties panel?
Farther along down the process I’m getting what appear to be frame blending issues like you see when you pick an export setting that doesn’t match your source frame rate. I’m just trying to figure out where my mistake is.
Thanks in advance for any help!

Hi Nate,
Change PULLDOWN to NONE, currently set to 3:2. As the Source and Destination frame rates match, there should be no pulldown/conversion applied.
Is HD2SD still necessary? I can’t speak the Progressive HD sources, but my HDV cameras are 1080i and I’ve tried it all within Adobe and have never gotten great results when making DVDs. Always having flickering due either to scaling, field issues, or combination thereof. Plus for longer videos (2+ hours) the compression is quite evident.
I use HD2SD to convert my 1080i HDV footage to 480p DVDs with beautiful results.
I should note that the Bellune method may be a bit dated, using the older MPEG-2 conversions. I use the Lagarith lossless AVI codec instead for my intermediates. This creates an .avi with the YV12 color space that HC Encoder needs (you are using HC Encoder?).
Please PM me and I can send the entire workflow that I use including HD2SD recipe.
Thanks

Hey, thanks, Jeff! I would love to see your workflow. I didn’t get a chance to test the pull down suggestion yet, but I’ll bet that’s it. I ended up just exporting from AME and it looks fine for the footage I had, so I’m sticking with that for this project anyway.
I don’t see how to PM you on Creative Cow. If you could e-mail me the workflow, that would be amazing!
I’ve got contact info on my website (link in my signature below). Thanks!

hi Jeff,
I’ve read about the HD2SD workflow process recently, but have not tried it out. If you don’t mind, please send it to kissupandu@yahoo.com.
I capture using MAtrox to MAtrox MPEG-2 I-frame HD AVI files.Thanks

Im trying to get the HD2SD workflow down. I was wondering if you could help me out?
Thanks!

HD to sd… …Pulldown only needed when the frame rates don’t match.
Just for those taking notes, I use AME to output 2 files, an mpg2 video only, and an mpg2 compatible audio for encore (when I’m going to sd or Just DVD). I chose a VBR setting though. It allows the file to shrink more without losing quality, and I can fit more onto a disc. Constant bit rates can be a bit sharp in some areas and not as sharp in others. It can look tacky.

Ht,
The ONLY format that works for Encore without transcoding is “MPEG-2 DVD” which results in an .m2v video file and either .wav or .ac3 audio depending on your settings. If using a regular “MPEG-2” video export format, that is incorrect and will need to transcode (encode AGAIN) in Encore.
Thanks
