Does anyone here transcode first?

[Wagglerock]

Just wondering if anyone here transcodes their dslr footage to an intermediate codec before editing. I'm using gopro studio to transcode to cineform avi's before editing in vs. Seems to work better than the raw h.264 files from the camera. Anyone have any other workflows they'd like to share that might work better?

A bit unclear on what you are really doing. There are several hundred "flavours" of avi so you will have to post the properties of those avi files in order to have any meaning. Any time you re-render a video to another format there are quality losses.

What do you mean by "the raw h.264 files from the camera"? Did you first copy the files from the camera to your computer or are you editing directly the files from the camera?
What does "seems to work better" mean?

No I don't, though I have experimented with GoPro Studio to transcode Hero 3 mp4 to .mov files. But I only did so as a one-off experiment. The results were OK. But I have no trouble with the original footage anyway, so don't find it necessary to transcode.

What problem specifically are you having, and can I assume it is with GoPro video? If the video stutters in VS, you might want to look at the solution found by another user: http://forum.corel.com/EN/viewtopic.php ... 50#p305950

Sorry about the lack of info. I was experiencing stuttering with my canon dslr clips. Particularly on pan shots. After digging around online I found this solution. Take the MOV h.264 files from the camera, use gopro studio(or mpeg streamclip ) to convert the files to AVI files with the cineform codec. Some folks convert to avids dnxhd codec. Use these files to edit because NLE's like to use codecs with intra frame compression. Edit, then export whatever you need. That method works ok, but it's not perfect. I was wondering if anyone else found a better solution. I'll check out that other solution that you mentioned, thanks!

I'd like to add that the file from the camera plays perfect in windows media player or qt. The problem comes when it's rendered out of vs if I edit only with the camera files

[Ken Berry]

Can we assume you have Quicktime on your computer? If so, which version?

[Wagglerock]

Yes, latest version. Updated it last month. Don't know the number off hand. Using vs x4 ultimate. Funny, files from my gopro hero work flawless, the trouble is with my canon 600d.
Some other stats:
Windows 7 pro 64 bit
I7 processor
8 gigs ram
1 gig of video ram

surly Intra frame codec is better Wagglerock than long GOP one.
Can you upload a short clip for us to test in X8 and other systems?

Hi Wagglerock

I am assuming the problem is with editing and timeline playback and that the final rendered video is ok?

I own a Canon 7D, a good DSLR still camera with video capabilities, I assume produces the same video as your 600D? my main video camera being a Panasonic, as such I don’t use the Canon that much for video recordings.

The clips are poor when playing in the timeline both Clip and Project modes.
To help I have to use Smart Proxy, at least Project Playback improves, however Clip Playback is still a little poor.

As I say I don’t use the camera for my video only taken short clips. I would imagine the playback issue to be worse with longer video.

Try enabling Smart Proxy, make sure proxy files have been created for all clips, the process does take a while.

If you do feel the need to convert the originals you may be best converting to your output format.
What are you trying to create, a video for the internet or a DVD / Bluray disc.

[Wagglerock]

Yes I do believe the 600d produces the same video type as the 7d.
My problem occurs in the final rendered product, and I always use proxies when editing.

I'll see if I can find some good examples to post here

Hi

Samples would help, the original and the rendered version.

Unfortunately I am on holiday as from tomorrow so wont be visiting the forum for a week. But will look if you manage uploading today.
I am sure other will find the samples useful.

You did not say what your final rendered product is, what are you making?

[Wagglerock]

Trevor, thank you for your time. No rush on this. I'll film something this week to replicate the issue and do before and afters. I'll post it here.

Thanks again
Mike

I never transcode or work in proxy files. It has to do with your computer's processing power whether you have a good editing experience without adding doing this.
I edit GoPro Hero2, Canon DSLR, Canon AVCHD, JVC AVCHD and another action cam (mov) files with no problem.
And file that VSP does not like, I use a free program HANDBRAKE that will convert (and batch convert too) files to something VSP can easily handle.

Now, I have heard of people that use GoPro's tweaking Cineform have some issues, but since I have never used their ancillary programs, I can not give my impressions.
