transfering large video files comp to comp

[rotuts]

Well this is a little OT and really relates to any large file transfer but ive always gotten such excellent help here Ill ask,:

i have large video files from my Alchemy card ( 2GB/30 min tv sorensen3 320 x 240) and DIVCO (700MB/30 min MPEG2 640 x 480).

I plan to get a G5 dualdual in aabout Jan or so, and now realize Id have to get new PCIe cards to replaace these i have for my G4dual1gz w PCI. the cards probably do not exist (yet)

having learned about FW400 vs 800 on a previous thread, those tranfer rates, what can I expect in tranfering these large files via ethernet connection between my current G4 and the new G5 DD, assuming Id want to put them on the g5 for processing to smaller 3ivx files.

currently it takes about 20 min to recompress a 26 min sorensen3 file, and streamclip 1.3.x takes about 'real time' to do its work.

any thoughts? do I need to bite the bullet at get new cards for the G5? or use the bridge Ive seen mentioned comming out that might fit in the G5?

thanks sorrry if a little OT!

You have multiple questions.

Re: Ethernet - connect them together and check if you get a GigE connection. If so, connect via filesharing and drag the files over. Get a three-course meal with dessert.

Re: Bridge - No answer until is ships and is reviewed. Probably will need a new card is my guess.

Wow rumps Id knew youd answer. and I knew this was going to be a real pain

guess id have to look into new cards. I love the alchemyDVR card, but I acually use there v 1010 rather than 241 as the recordings interface on 1010 is like an excel sheet: you can navigate by column etc

there newer recordings interface is just a list and takes up a lot more room/line and you can't check by catagory etc and that only works in 10.4 the older does not.

so maybe Ill look at el gato

maybe ill just stay in a blind end!

thanks

bet you check hardmac daily, huh?

Rumps: new idea:

what about having the two computers conencted as a network via the ethernet cards, then have the file created on the G4 saved in real time on the g5?

thats the key: the g4 will only make a 320 x 280 w sorensen3 as the real time compression as anyting bigger will get the audio out of synch.

and again Im not looking for a very large file for the final keeper: they run 100 to 150 MB as 3ivx files.

I think something like the EyeTV may be much better for your use. It's an external box so moving it to a newer Mac is simply a FierWire plug. The encoding is done on the EyeTV box. They update the firmware periodically to provide new codecs. On a dual-G5, you should get close to 2X real-time mpeg4 encoding from the content coming into the Mac from the EyeTv. It is possible they may (already or soon) provide mpeg4 encoding. I'm already taking content and using mpeg streamclip or iSquint or MoviesForMyPod to create iPod-capable media. If you use mpeg4 you'll have up to 480x480 (well, 480x360 for 4:3 and 480x270 for 16:9) with up to around 2500kbps bitrate although much less is fine). The resulting clips will play in your iPod, through the iPod to your TV, and will not take up too much HD space.

I realize this opens up a whole other area for discussion but, before you go much further down the road, you need to stop and look around to see what is rapidly becoming the standard.

I should mention that the 480x480 pixel size is really meant to define the -total- number of pixels (230,400) that the iPod will handle (according to Apple). Therefore, any ratio of pixel sizes that does not exceed this limit should display on the iPod just fine.

It's the H.264 codec that is limited to 320x240. In this case, I am not sure whether this means 76,800 pixels or if there really is a hard maximum limit of 320 width and 240 height. I know that 320x240 works as does 320x180 for 16:9 source media.

great thread

I save PBS/other cooking shows mostly. a hobby

some pbs digital has woodworking shows Id take those but they are rare.

I must have about 1000 ( really ) rachael rays 30 min shows.

there is better.

after all, I have to eat. no intererst in iPod movies right now. I watch on my digital monitors

el gato didn't have the flexability that the AlchemyDVR card had at the time I got it and was 2x the price.

will wait and learn until jan 2005. I get over the air HDTV now NFL etc
