Editing in HDV - I've not got the power

zazentao wrote on 7/17/2006, 1:39 PM
Hellow everyone. I am new to the editing (and videoing) world and so naturally am experiencing problems.

I have a Laptop of reasonable performance apart from one factor I get different opinions on, and that is the fact it is a CELERON 1.30GHz. If I try to edit in HDV the footage is too jumpy to do anything with? Is there anything I can do - besides buy a new computer - to get around this problem e.g. down convert to SD.

I am only looking to do a rough edit on my computer so that I can hand it to a pro to do the real thing with...I just need to be able to sift through about 30hours of footage to get some sort of storyline together.

Any and all advice is much appreciated! :)

Do a search for HDV Workflow and you will find a post by johnmeyer that goes into detail how to work with HDV. Also, if you can work with standard def. footage, you can definitely use the cineform intermediary codec to work with HDV.

You might want to take a look at our GearShift tool. It can batch convert all of your HD footage to DV so you can work on it at DV speeds on your laptop. Then before you’re ready to render, it can swap out all of the DV footage for the original HDV footage so the project maintains its HD quality. There is a 15-day trial if you want to see if it fits your workflow.

1.3 GHz is not going to let you have much fun editing HDV using intermediates. You can do it using proxies for sure (identically the same performance as editing regular DV, since that is exactly what you're doing), but the render times for the proxies and for the final render are going to be painful.

I realize that everyone has their budget, but you can get a lot of computer for just $500-800 (if you already have a monitor). You'll get 3-5 times the performance of your current computer.

I agree, with that machine the proxy method is the best option, and I can recommend Gearshift. I use a 1.6 GHz Pentium M, and with that I can edit a Cineform intermediate with reasonable performance; though I have to reduce the preview quality to get a full rate preview even on a single track. The time to render the proxies isn’t that bad (about 3 or 4x, if use the “good” setting), but for the final render (where I use “best”) it’s about 10x!

Thanx for all the advice everyone! :) Now all I have to do is look up things like 'intermediates, proxies and codecs' and I should be laughing! hahaha As you can see, I have a LOT to learn.

Perhaps I will try the gearshift program to start...I have a desktop also, but will be going on the road for quite some time so wanted to keep on top of editing whilst I am out of the country.

Thanx again! :)

I'll give you a simple answer... you can search around for a more detailed one:

Intermediate: A format which is easier to edit (think "DV like, but HD"). You render to this intermediate (Cineform codec within Vegas), and edit this. When done editing you apply the edits to the intermediate to get your final render.

Proxy: Here you render to ordinary DV (Standard Def) and edit that. Then when you are ready to render you swap the "proxy" with the original HDV file. That way the render uses the original high quality HD file... but editing is faster as it is on the DV file.

You can do proxy editing withou Gearshift by manually replacing files, but if you have multiple files it gets confusing... this is what makes Gearshift worth it.

Mark: Excellent summary.

zazentao: I used a dual cpu 1Ghz pentium III for about 9 months with my FX1 HDV footage. Proxy was the way to go. Playback at HD was not good, but you there are more options now (DVD set-top boxes that read and play HD wmv files). You can always print to tape back to the HDV cam and view on HD TV for final checking.

Note: for real speed at rough preview, you can go with 360x240 proxies, also. Depends on how much detail you need.

Proxies need to be the exact length as original clips, I think, for clean replacement on the timeline for final output.
