Specific MPEG Streamclip question

I'm using MPEG Streamclip to convert my raw 7D files into Avid DNxHD codec, can one of you guys share a method for batch converting? I was doing this one at a time before, because when I would select mutliple files in the window, bring them into the program and then export, it would stitch the files together and spit out one big file. Just wondering how I can still batch process but tell Streamclip to maintain individual files.

Thanks for any help.
 
open mpeg stream clip
click lists>batch list
add files
continue with normal settings.

its pretty simple once you actually start doing it.
 
I will say this. I did this for a project recently, and I was not happy AT ALL with the conversion. I'm not sure what's happening inside the program, but I was completely unhappy with how the conversions came out. It's not like that when I do the conversions from my NLE.
 
Streamclip shouldnt be used for transcoding footage unless its going from a master file down to an H.264 for web viewing or something less demanding of quality. It slightly pixelizes most codecs during rendering (easily seen in text on black)
 
I concur with Andrew, everything I've done with MPEG StreamClip looks better than Compressor.

After you place your clip into the batch window and it asks you what you want to do, you have to go into the advance settings and change to compression quality to 100%, for some reason it defaults to 50%.

The first time I used it I thought it was crap but after tweaking it a bit it is faster and better than Compressor IMHO.
 
I converted 6 days of Canon 5D footage. The blacks didn't pass muster. I threw them all out and replaced them with the original files in the workflow. The difference was immediate and obvious.

Mpeg Streamclip is off the table for me for DNxHD conversions. And it crashes doing Jpeg2000 conversions for me. However, it works like a charm for my mjpeg draft work. Or if I need to take a group of masters and make low-res comps I'll use it. But I wouldn't rely on it for any master or archive file.

Surprised to hear you say this because a lot of pros--including the likes of Phillip Bloom, Stu Machowitz and Vincent Laforet--are using streamclip as the first step in their worklow to create prores 4:2:2 for editing. They specifically reccomend it over compressor.

In my own experience, streamclip conversions are flawless, pixel-for-pixel indistinguishable from my NLE output.
 
I'm having better luck with streamclip over neoscene. Not sure anyone else has noticed this but I've seen some nasty noise introduced from neoscene that's not present in original footage or in the streamclip transcodes.
 
I think we need to back up here a moment. There's a wrench in the works...

Mpeg Streamclip for Mac is not the same as Mpeg Streamclip for Windows. The Mac version appears to work awesome. The Windows version has been somewhat abandoned. This might account for the huge disparity in success with conversions we're talking about.

Personally, I am on Windows and my experience has been quite poor going to DNxHD and Jpeg2000.
 
just did some test shots, batched through Windows version of MPEG Streamclip into DNxHD into PproCS3...viewed at 100% of before/after I see no issues here.
