Exporting to WMV 40MB limit ?!
I’m editing AppleProRes KiPro 1080 files into 30-40 min pieces that need to be exported to WMVs w/ a 40MB limit.
Anyone have any advice on the best workflow from edit to export to wmv? I do have Wondershare Video Converter. The size limit is mandatory…I’m just looking for best quality – even if I need to dip down to the 360×240 size. Or a little less quality at a bigger size if ppt slides can still be readable.
TIA!!

With that limit they’ll probably look absolutely horrible or be the size of postage stamps.

That’s a pretty strict limit! With those lengths and that hard cap you’re looking at about 165kbps as your total data rate for both audio and video. So you could apply 100kbps towards video and 64kbps towards audio. You won’t be able to go much beyond 320×240 (or 320×180 if widescreen) as a resolution. And likely even that resolution will break down and show significant softness and blocking with those reduced data rates.
But Tero’s right. Your choices there are it looks bad as a bigger size or it looks good but is the size of a postage stamp. I’m curious why the hard limit and why WMV?
Here’s Vimeo’s Compression guidelines for what they recommend when you upload to their service (not your use case but it gives you some size/data rate guidelines that I think are pretty useful overall) – https://vimeo.com/help/compression

Whatever the reason the client needs this is neither here nor there. They will see after the files are delivered that it is unreasonable to fit that much data into a 40mb file and have it look good. Make sure to keep notes so you can educate your client for future encoding projects.
For the WMV If you are on a Mac is Episode pro. As it will give you the most options.
When you run your test passes, take a small portion like 10% so you can roughly estimate time and size.
I don’t have any Experiance with wondershare but I would recommend episode pro

Thanks. Yes strict guidelines for company’s intranet. I’m suggesting 15min segments..but still doing tests. I’m using Quicktime Pro w/ Flip4Mac Studio to export to WMV. I’m playing around with CBR 300 (16×9) and VBR (different modes).
Question: In reality, I’ll be getting kipros 1080 APR which I’ll need to edit. Will testing a workflow from another 1080 source be comparible? I’m basically exporting APR from Premiere Pro, then letting Quicktime do the export.

Right now, I’m testing w/ Quicktime Pro w/ the Flip4Mac Studio version.

@Kris – I agree. I was just curious about why. It feeds my fascination when people demand extreme things. And, like a 2 year old, I just like asking “Why?!” all the time! 🙂
[Heather Brown] “Will testing a workflow from another 1080 source be comparible?”
@Heather – It really won’t matter what you’re source material is as the limitations, as they currently exist, will render most everything as a varying level of bad. If you can cut down the length as you suggest to 15 minute segments that would allow you to up the total data rate to around 450kbps, which would be markedly better than before. If you ran your videos through at 320×180 at 450kbps, you might be satisfied with that……?
If you’re source material is HD, then you should prepare yourself or those in your company to know that these data rates do not sustain video well. It will look soft, blocky, and not at all like the source material (unless you make the resolution very small). It’s completely possible to get something done within the limitations, but what quality level you’re willing to accept (or the company) may be where the rub lies.

If the main purpose is to compress the living crap out of these files to 40MB…will the compression quality be better if the footage is shot to kipro in SD or 720 vs. 1080?!

It probably won’t make a huge deal of difference. But I don’t think your final compression should be the arbiter of what resolution/quality you shoot either. I would say that you’re better off shooting 720 or 1080 so that you can reuse it down the road for other projects (or if they want it re-encoded at better resolutions later). I’m a firm believer in the garbage in, garbage out mantra. I always try to shoot the best image I can to start with, regardless of delivery format/codec/compression. You never know (especially in a corporate environment) when you may need to reuse or redeliver that footage. Having the added resolution is helpful. Plus you can pan & scan on the footage if necessary today because you’re going down to such small frame sizes….so it gives you more leeway in post.

Exactly. Just wanted to confirm my reasoning to the client. Thanks!
