frame export
Maybe I’m missing something obvious, but when I export a frame from a 16:9 project in premiere pro 2, it comes out squished up to 4:3. Even when the export settings say to export a 16:9 frame, I get this problem. Any suggestions on how to get the right ratio?
Thanks,
Adam

This behavior is correct for anamorphic material. This means the PAR is 1.2 and the picture looks distorted vertically in a 4:3 frame. PPro is accounting for this internally when displaying it for you in the source and program windows within a 16:9 project. This same project/material when viewed on a 4:3 external monitor would look distorted as well unless that monitor also has a 16:9 switch or mode enabled. What it’s doing when you export a frame is giving you the true, original frame without adjusting or accounting for the 1.2 PAR. Personally that’s what I would want in that situation so that I then have control in a image editor to make adjustments I see necessary. I would have the control, not the export routine of PPro. I suppose as well that if there were such a export function available that what you may get would be a letterboxed frame.

Great suggestion, but I’m not using anamorphic material. At least, it wasn’t shot that way.
I need a (hopefully easy) way to export the frames at their native ratio so that a less-than-sophisticated imaging program I have to work with on this project won’t squish ’em. We’re talking about hundreds of individual frames, so if I don’t have to run them through photoshop first, it would be a huge time saver.Thanks,

So, if it wasn’t shot anamorphic, then your source and preview monitors (and project settings) should be for DV Standard (not Widescreen), right? And you should have 4:3 shaped PPro monitors which show the letterbox, correct? If so, then you should get a letterboxed frame export. If not any of the above and your project is 4:3 anamorphic (DV Widescreen in PPro’s setup dialog when opening new project), but you shot LB, you will get stretched frame exports as the Widescreen 16:9 project assumes a PAR of 1.2 and processes treats the exports as such. But if you shot LB, all of your material must appear to ‘float’ in a 16:9 project unless you scale it up, right? This is what happens here when I test anyway. Is this what you are really wanting to do? As for re-scaling a bunch of stills, you can set up an action in PS to do this easily and painlessly and it doesn’t take long. Or import them all into AE at 1 frame duration and export a image sequence after resizing. Hope this helps a little.

Thanks.
I’m still getting the hang of the whole production studio workflow. I bet that’s obvious. I shot this stuff in HDV, so I get 16:9 monitors. I thought it was native, but if PP2 treats it like anamorphic, then that explains it.
Thanks again.

I’m sorry, I should have asked what format, I assumed SD. Depending on what HDV format you shot, the results you are seeing could be how PPro handles things. I don’t personally know ’cause I’ve only tested HDV very little in PPro. All HD formats at their native uncompressed and true pixel size are square pixel which is great. However, Panasonic uses 960×720 and Sony uses 1440×1080 as their pixel size for what’s recorded on DVCProHD @ 720 and HDV/XDCAM/HDCAM respectively. I think, but I’m not positive, that JVC’s is true 1280×720 and is square pixel. Only Sony’s XPRI system can edit HDCAM natively in it’s codec, so that’s not really an issue for most folks using HDCAM- we see it as 1920×1080 out the SDI spigot on the deck. The same is true of DVCProHD out of SDI from a deck- you see 1280×720 square, the deck does the de-squish. But everything else (I don’t know how XDCAM’s MXF files behave- I’ve never seen one) in it’s native format (save for JVC’s I think) is a anamorphic-like thing to save on file size. I haven’t ever tried to export a frame from a HDV project in PPro and don’t have any HDV material handy right now to try, but I bet it’s this issue that’s causing the ‘squishys’. FWIW, I just tried exporting a frame of DVCProHD native 960×720 from FCP and the resulting frame looks anamorphic. I would imagine that this is what’s happening in PPro too. Good luck!

Thanks again. This was my first shot at posting on any user forum, and you’ve been most helpful.
FYI, I shot this job with the JVC HD-100, which is 1280×720 native, so if this is what’s going on then the JVC format must not use square pixels after all. Maybe on the newer camcorders like the HD-250 it’s different, but I don’t know anything about that.
