Re: best format for USB delivery
 

Thanks guys. I hadn't considered the fact that I would need some type of hub or duplicator to deal with quantities. A couple flash drives for a wedding are one thing, but 50 or 100 for a recital quite another..
Now I need to look more into this

Re: best format for USB delivery
 

So it sounds like USB 2.0 isn't a good idea due to much slower speed. I found some name brand for $3 on clearance at walmart I was about to buy but now I'm thinking I should spend more on 3.0 ?

Re: best format for USB delivery
 

What are your thoughts on duplicators such as these?

and standalone

Re: best format for USB delivery
 

In this type of work besides time, media is the largest part of your expense so you want to spend as little as possible. The highest quality dvds are only $.60 and take only 6 minutes to burn where as the cheapest usb 2 flash drives start $2.50 and can take 20 minutes or more to copy. I buy 16gb SanDisk Cruzers for around $5, they're slow usb 2 but very reliable (never had a problem or customer complain). I am still thinking of going to either less expensive generics or to the usb 3 so I don't have to waste my time.

Be aware of that there are 2 bottle necks with flash drives. The first is the memory speed and the second is the interface. A lot of the cheapest usb 3 drives have the faster interface but still have slow memory. I always like to read a performance review or buy a few and test out whether the price/performance is a good value.

Also note the flash market prices can fluctuate greatly. Last year there was a shortage and prices shot up.

Re: best format for USB delivery
 

no complaints so far about the usb stick from clients. Now I have 2 complaints.

2 times the brand of the tv is "philips" that causes problems.

From 1 I have been to the clients home. The strange thing is that some chapters play and others not.

On their tv upstairs they said everything is fine (no philips brand tv)

Normally they all have the same codec MP4 and the usb stick is FAT32.

First I exported from sony vegas pro to a MP4 file and in handbrake I resized it.


I downloaded the testvideo from philips that should work.

With mediainfo I got this:

video stream: AVC and audio stream: AAC LC
MPEG-4
main@L4
24 fps

when I checked my handbrake file:

video stream: AVC and audio stream: AAC LC
MPEG-4
main@L3.1
50 fps

So the mail level is different. Maybe that tv It doesn't support a lower 3.1 level ?
Framerate is different but normally that couldn't be the problem.

I don't know how to solve this. any thoughts?

Re: best format for USB delivery
 

update: made a new usb stick with the same files made by handbrake.
Went to the client and it worked!

At home I tried that bad usb stick. And yes, only chapter 1 played on my tv and on my pc.

When I inserted the stick in pc it detected a problem. after I did a scan, removed all the files and copied 1 chapter and this time it worked.

Maybe there was a problem in the beginning and I ignored it, don't remember it.

Re: best format for USB delivery
 

I see my last reply was about 6 years ago. I still deliver to usb 2.0 but tis time I have glitches in the video files when playing it.

I saw to speed was dropping from 6 MB/S to sometimes zero. Maybe a bad flash drive.

But the question is: do you still deliver in fat32 these days. I read that NTFS is "much" faster then FAT32 on a flash drive.

Re: best format for USB delivery
 

Sounds like a bad drive. I have been delivering MP4 on NTFS formatted USB drives for a couple of years now and not had any problems from any of my customers. I've been using Kingston 64GB drives which I can buy from a local supplier for around £3-£4 each. They are cheap but fast enough to play back 4K at around 30mb/s. I produce recordings of stage shows, and 64GB allows me to deliver an edited version of the show and also a 4K wide view of the show for anyone with a large 4K TV. It also gives me scope to experiment with HDR in h.265 in the future.
