Hey,

Basically I've filmed some stuff in 720p 60 frames per second on the 550d with the RAW format. I did all my settings etc and then put the card into my comp...

Obviously the natives files were VERY choppy on CS5 SO I downloaded MPEG STREAMCLIP and now I'm stuck... I'm not sure to what codec I should change my footage into? I've heard avid DNxHD is good but I tried that and it just did audio files...

I've seen one guy who uses 550/t2i and he said he converts his files from the camera to HDV then edits (for smaller size) and exports to 720 60 quicktime for web.

So if someone could please help me out with what codec and exact setting to change my 550 footage into i'd be very grateful !!!
 
Is 720 60p the delivery frame rate, or were you trying to shoot for slo mo effect, and need to conform the footage to a different frame rate?

What's your NLE? Premeire CS5? Avid?
 
No I was filming in 720/60 because I have seen another 550d skateboard filmer using it and it works perfectly... So I just need to convert the native files into something less choppy/slow in Premiere Pro CS5
 
Are you delivering in 24p or 60p? Why are the native files choppy in CS5? What are you computer specs?
 
download demo of premiere CS5; if the native files of the card is choppy even now, you definitely need a new computer.
 
I'm just curious... the whole question of the 60p workflow notwithstanding... why 60p and not 50p? If you're in London, you're in PAL territory, which means the native time base for video there is 50i or 25p. 60p is not compatible with PAL video, unless it is conformed to 50p (in which case you do get a slight decrease in playback speed). So why are you not shooting in 50p rather than 60p?

Also, converting to HDV is an odd idea. Have you thought about DVCPRO HD? It's a perfectly suitable, and very manageable editing codec.
 
Once I put the native files onto the timeline and render they actually play fine... so I guess that clears stuff up! and I do 720/60 ntsc purely because ntsc is better for web upload.
 
OK, I'm using mpeg streamclip and converting the OG files which are about 27mb (10 second clips) into dnxhd codec and they then change into 200 odd mb files... /: this doesnt seem right? I'm on a lose end. I've got a decent enough comp... core 2 duo etc and I can run cs5 fine but the clips are super choppy.. help?!
 
An intermediate codec will yield larger file sizes than the camera's h.264 codec, but will be easier for your computer to playback and edit.

If your computer doesn't have a supported graphics card, Premiere CS5 might not be able to decode multiple streams in real time.

p.s. How old are you? Your spelling and syntax are awful, I have to read your posts several times to understand what you're asking.
 
Ah I see... I was just bewildered at why it was making bigger file size's than the original! Thank you for your input :) I've just downloaded neoscene and apparently the intermediate codec on there is pretty good, it's also only making slightly bigger file size's than OG so it's easier on my HDD

Click to expand...

h.264 is a highly compressed GOP codec, which means Group Of Pictures. In other words, there aren't 30 actual frames recorded (or 24, 25, 60, etc.) Only a few full frames are recorded, and all the frames in between are recreated upon playback by, essentially, "connecting the dots" between point A and point B. It does this to save space; hence the small files.

When you convert to something like DNxHD, Cineform, ProRes, DVCPRO HD, or even DV/DVCAM, you're converting to an I-frame codec. It actually writes out all the "in between" frames that don't exist in the h.264 file; hence the larger file size. DVCPRO HD, by the way, is a perfectly good editing codec if your computer struggles with DNxHD or Cineform.
 
Ah right I see Alex! Thanks for the explanation... never really knew that much about the codec so yeah, was cool :)
 
I've been using Cineform Neoscene for 6 months and never looked back. I Vlog often and Neoscene converts my T2i footage like a hot knife through butter! You made the right choice.
