One hour of video equals 13 GB, right?
Howdy gang. I haven't been here for around six months. Been busy with website stuff. Now that that's done, I can get back to video work. Yeah! The forum looks a bit different, but it looks like you guys are still a super funny and really helpful group.
Here's my quick question. My boss wants me to put everything I've ever shot on tape into my computer. Now, I know the old saying, one hour of video equals 13 GB. But to be clear, and to be sure I don't buy a harddrive that ends up being too small, does that mean if I capture a one hour MiniDV tape it will take up 13 GB on my harddrive? Or is it 13 GB for an hour that's been exported as a QT movie?
I should know this. I'm embarrassed for not being sure. But I get kinda panicky and second-guess myself when it comes to asking the boss for new equipment.
So am I right in figuring that a 500 GB drive will hold footage from about 38 one-hour MiniDV tapes?
Thanks!
jbell brings up a good point.
Drive manufacturers sell drives with space calculated in decimal, while the computer sees space calculated as binary.
To a drive manufacturer, a gigabyte is 1,000 megabytes. To a computer, a gigabyte is 1,024 megabytes. Therefore, when you buy a 500 GB drive (500,000 MB), it's actually only 488.2 GB to the computer (because 500 GB would be 512,000 MB).
And when an hour of DV is said to be 13 GB, that's 13 * 1,024 MB, not 13 * 1,000 MB.
If you go by the binary prefixes outlined in this wikipedia article (which have yet to gain traction), a computer's gigabyte should be called a gibibyte (GiB).

Why is one hour of video 12 gb????
I have never experienced this before. I import one hour of video and idvd complains that it won't fit (even on a dl dvd). I look at the clip info- 12 gb!!!.
I have never had a problem making idvd projects on this imac g5. Is there something suddenly wrong with the compression?Hi theresaa:
The file size for uncompressed DV material is 12 GB for one hour of video so that seems correct..
And, a DVD holds a maximum of 120 min of video regardless of the original file size.
Use File / Share / iDVD and it will automatically compress it to fit.

I have edited a movie in Final Cut Pro and the video has been smooth all the time.
Now, when the one hour long movie is ready the video seem to paus every 5 sec (only for half a second). It does it all the way through the movies.
What is wrong? All the sudden.We need info, info, info!
What version of FCP X?
Did you render? what are the project specs? do you use many compound clips? how much ram, hard drive space, how is the hard drive connected?
It looks like your mac can't keep up. Maybe the bottleneck is the hard drive, or something else.
Try exporting a master file and see if the video is ok.
Also, keep Activity Monitor open and see how much memory pressure you've got. -
Premiere Elements -Saving part of one hour video
Imported from only VHS home movies into Premiere Elements 8 a one hour video. I would like to just flag a specific segments, such as minutes 4-8 and export that to a new avi file. After that I might want to export minutes 12-20, etc.
To date I have been cutting and deleting everyting except what I want to save, saving that file, then importing the original file back into premiere and cutting and deleting everything except for what I want on the next file.
Seems like way back when, I was able to save various segments of an open file, but not sure.
Any help would be appreciated. Tried to ask adobe when searching for answers about Premiere 8 crashing so much, no problems with 7, but they refered me to Adobe.TV, where I did not find any answers. Maybe in tutorial, but not able to find it.
Thanks in advance for any helpHere's a look at the WAB (Work Area Bar), and how it's set. Note: this is from PrE 4, but should be the same in all recent versions.
Hope that this helps,

2011 MBP (10.8.4) freezes exactly one hour after reboot
Hello,
I'm having an issue identical to this poster insofar as I can tell, but some test results are different for me. Exactly one hour after rebooting or starting the computer, applications become unresponsive, video stops playing, then a little while later sound stops playing, and the cursor becomes a beachball if interacting with an application. Some windows can still be dragged or brought to the front of the screen for a short time. Eventually everything (except sometimes the cursor) is frozen and the machine never recovers from this state (for at least 15 minutes, I haven't let it go longer).
Most of the time this is accompanied by a CPU use spike and the fans spinning up, but not always. I have trawled through the system logs and disabled lots of LaunchAgents to no avail, so let me just list a few things I've tried and their result.
Disabling wifi: no change
Removing RAM one slot at a time: no difference
Memtest: clean results, froze after 1 hour anyway
Apple Hardware test: clean result on extended test, progress *sometimes* halts at the end of the third or fourth pass after the "Main Logic Board" test had finished (during message "Testing in progress... Extended testing in progress").
System console/system.log shows no distinctive output immediately before freeze, unless I'm doing other things like playing audio or using the internet in which case the wifi interface has activity or CoreAudio turns outputs on, but this is different every time it crashes. I did find that GoogleSoftwareUpdate was implicated in one of the console logs, so I disabled and uninstalled that without effect. I recently started using Time Machine on an external drive, so I disabled that and removed the drive I'd selected from Time Machine preferences - no improvement.
While watching Activity Monitor during one freeze, I saw that cprefsd (root) had spiked to 260% CPU usage, fseventsd (root) to 128%, and several other processes to 100% (UserEventAgent, cprefsd, iTunes Helper, and apsd (root)). Everything else was at 1%.
Symptomatically, this appears to be a software issue (not an instant crash, elevated CPU usage, regular timed interval), but I've been unable to isolate the cause. I strongly suspect Time Machine is responsible (fseventsd is linked to it) but having disabled it in System Preferences I'm not sure if it should be eliminated. Alternately I believe this may be symptomatic of logic board, memory controller, or graphics card failure, but am at a loss to explain the regular (non-random, non-usage-dependent) occurrence. I performed the syslog test prescribed by Linc Davis in this thread and found only regular shutdown codes, so that also seems to point to software issues.

This morning I tried leaving the computer on in Safe Boot mode and the freeze occurred on schedule, with the windows becoming unresponsive at 60 minutes in, and the the beachball appearing as soon as I moved the cursor.
If I can get a full backup sorted (only essential stuff is cloned right now), I'll try a clean install of OS X from the recovery partition to see if it nixes whatever process is at fault. I have an appointment with the Genius Bar tomorrow evening, but if this is really a software problem then I'm not sure how they can help (except to replace it at cost). Are there any other tests or fixes I can try? What's the likely prognosis?
Thanks a lot for your help.Apple replaced the logic board and the fix and it didn't fix the problem. To their credit, they refunded the repair fee. I ended up tracing the issue to a third-party drive I'd bought from NewEgg, a Crucial M4 SSD, which had a very peculiar firmware bug:
Correct a condition where an incorrect response to a SMART counter will cause the m4 drive to become unresponsive after 5184 hours of Power-on time. The drive will recover after a power cycle, however, this failure will repeat once per hour after reaching this point.
I would have probably gotten the update notice had I purchased direct from Crucial (or had it come pre-installed if I'd bought it a month later). If you have a similar issue, check your drive firmware! -
I can increase the record time of one hour on my iphone 4?
I could not record more than an hour on my Iphone 4 of 16 G.
The one-hour video occupies 3.5 G. I have 10 G free others so that space is not the problem. Are there any special configuration program or to record longer?
It can record lower resolution?
Thanks for your helpYou double posted.
Open the Video app on the phone, locate the movie, swipe from left to right, hit delete. -
Merging two versions; one w/PAL Audio one w/NTSC Video
Here's an oddity...for a project was given a 2 hour video file in NTSC w/really bad sound levels. When I asked for it to be given a corrected copy, I got one with PAL video, with bad picture but great sound. Trying to get a third copy (third time is the charm) but for fun trying to see if there is a way to merge the two. First thing I tried was using the PAL Audio under the NTSC video (which of course didn't work, as the audio was longer due to frame rate, I assume). Then tried to change the length of the PAL audio in ProTools, changing it's speed by a small percent so the final length matched the NTSC video (fun experiment, but the synch wasn't at all right). Even tried converting the footage via Nattress, but no such luck.
Curious if there's anything else I should try for experimental learning...Hi Phrisbee,
If it is set to 1.5meg than that is fine.
I say downoad as it has to match this when people have a asymetric service like most (A)DSL services are.

14 hours to compress a one hour quicktime?
Can this be right?
This is how log it took me to compress a one hour quicktime (4:3 Pal) into an MPEG-2 for DVDSP.
Admittedly my iBook is not the fastest Mac around but this seems wait time seems... extreme.
Anyone have suggestions as to how I can speed the process up?
I was using the latest version of Compressor, and at the best quality 60 minutes setting.
The original file was 11 gig.
Thanks,
Jake.My little Mac Mini can take quite a while (30 minutes, even an hour) just to compress a few minutes of video while using Compressor. I have started exporting the file (as mentioned here) and then sending it to Compressor (rather than sending it to Compressor straight from FCP) and that does speed up things.
Your settings are completely different from the ones I typically use (I make a lot of H.264 for web), but frankly, I'm not surprised at the length of time it's taking. Compressor can be really slow. -
Vision m decreased one hour of battery in 4 month
Hi,
I have my vision m now a bit longer than 4 months. On arrival i did a battery check (to check if it was really 4 hours video). I could play a video with 25 minutes 2 times full, needless to say i was very impressed with the vision m. But last week i noticed the battery going down a lot faster! When the vision m is off the change is really noticable! When i fully charge it, 24 hours later is has lost one block and when using it for 0-5 minutes 2 blocks are gone!?So i fully depleted my battery, fully charged it and right after that it did the same test as when i just got the vision m... now my battery only last 3 hours and a bit when watching the same video :s:s?I did not use the vision m that much, let's say 5-0 hours a week and now my batterylife decreased with hours in 4 months ??Is this normal, is there a sulotion ?thank you very much(i buy creative products since soundblaster li've, i've also had a zen micro and a zen sleek and i've been always very pleased but now i'm a bit dissapointed...)??*edit*I just want to note, normally i don't fully decharge my battery because i know this is not that good for a lionbattery... so the one hour decrease is not from constantly fully decharging and charging to maximumMessage Edited by quinten on -2-200606:29 AM

TS's comments are BS. In fact you should fully discharge your battery to calibrate the fuel gauge.
Heat and time are the real enemies of li-ion batteries.
Here are some battery care guidelines from batteryuni'versity.com
Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns. <
Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely. <
Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level. <
battery life is still a contentious issue. there is a very nice thread in the archi'ves somewhere about it. However, people can spew out many theories about how you need to fully discharge your battery or else you will lose part of it, or how you need to partial cycle to avoid complete drainage etc...
remember that batteries don't have a "memory" they are a divided set of charged lithium ions and atoms. The batteries capacity will naturally deteriorate with time
I've always tried to keep some voltage applied across my batteries as this has never done them any harm. It's worth bearing in mind that many other factors including heat and frequency of usage are likely to be greater than any charging routine you have. -
How do I use "touch -t" to shift a batch of JPG timestamps by one hour?
I'm trying to use "touch -t" to shift a batch of JPG created/modified timestamps by one hour to fix a time zone error. Is this possible?
(I don't want to have to manually go to every file, and enter its current timestamp all the same way except for the month.)
By the way, does using the "touch" command have the same JPG lossy effect as saving the file again?picky picky picky
So you write a script that uses stat to get the current modification time and then add 60 minutes to it, with the date command, then then use that with touch against the file. Nothing to it
#!/bin/sh
find starting.directory -name "*.jpg" | while read file
do
ls -l "$file"
mtimeinsec=$(stat -f %m "$file")
mtimeplus_1H_in_touchfmt=$(date -j -r $mtimeinsec -v +1H +%G%m%d%H%M.%S)
/usr/bin/touch -t $mtimeplus_1H_in_touchfmt "$file"
ls -l "$file"
done
I've added an hour to the modification time. If you want to subtract an hour the +1H to -1H
If you want to use shell wildcard selection modify the loop to be something like
#!/bin/sh
for file in *.jpg
do
... the guts of the above while loop ...
done
If you just want to provide a list of files, you can change the *.jpg to a list of files. JUST BE CAREFUL OF SPACES IN FILE NAMES and directories
If you want a drag and drop application, you can do that with some additional changes and either using Applications -> Automator with the "Run Shell Command" or using Platypus (free download, and a very nice utility). The script would change to:
#!/bin/sh
for file in "$@"
do
... the guts of the above while loop ...
done
I have tested the very first script. I am fairly confident my 2nd to examples are right, but they are untested, so your mileage may vary. -
As stated I turned on my passcode lock to come on after 1 hour of operation. It doesn't work like I thought it would. My thoughts were that it would go to the lock screen and then require a code. Is my thinking not right on this? What am i doing wrong?
The passcode will be requested after the device has been in sleep mode for one hour. It does not turn off the device, nor is it a usage timer.

I imported an hour of video into iMovie HD and cut it down to a 33 sec clip, and emptied the trash. When I save the project, the file size is 20Gb. How can I save just the 33 sec clip?
Non-destructive editing is an important feature of iMovie HD 6.
iMovie preserves the entire copy of every clip you place into your movie in case you change your mind at a later stage.
So, if you have cut out one minute from a 45 minute clip, iMovie will have stored two complete copies of that clip. This is why is helps to set import as 3-5 minute clips rather than one huge chunk. As DV runs at 13GB per hour your project files can get very big.
One workaround is to complete the editing of a section of the movie, then export that to Quicktime: highlight the clip/s, choose Share-Quicktime, turn on Share selected clips only, and choose Full Quality from the pop-ip menu.
Once you have saved the stand-alone clip to your hard drive, you can re-import it into your project using the File/Import command, and delete the original long clip/s from the project. -
I am trying to copy more or less 30G from my MacbookPro to an external hard drive and it is stuck in the "preparing to copy" step. But that for more than one hour. What should I do to make it faster? Thanks a lot in advance!
Thanks Shootist007, by blockd files I mean files that I have changed to blocked and when I tried to move then for the first time, I had to unblock again. I am trying to backup my pictures, my songs and other files like word documents and excel tables. First I put all of them as blocked, what caused the first problems on trying to move them. Then, I've unchecked the block option and if I try to move one by one, there is no problem. The issue is to move all together, because it gets stuck in the preparing to copy files step. Anyway, if I cannot do all by once, I'll do it one by one, event though that was not suposed to happen if we are talking about technology, right? Anyway, I thank you again for trying to help me!

IPhone 3G Email and Calendar times off by one hour (slow one hour)
My times which I send/receive emails or put appointments on the calendar are 1 hour slow as compared to my computers. I have Mobile Me and Mobile Me (on the computer) and my Outlook emails and calendars match and my current time is correct on all. On the IPhone 3G the current time is correct but the time a email is sent or received and all appointments on the calendar are both off by one hour (one hour slow on the IPhone 3G).
I have set time automatically in "settings" to on, and under "email contacts and calendar" I have time zones disabled. I have tried each possible combination of these settings but cannot get the email/calendar times to match between my computers and the IPhone 3G regardless of how these are set.
I have numerous computers and all times are correct on all. On the IPhone 3G the current time (the clock) is correct, but times in emails and calendar appointments are all off (slow) by exactly one hour no matter what I do.
Anybody else have this issue, and/or know what the solution might be?
Thanks
The OmegaI have tried that and it did not work. I am now trying it with everything set to enable DST, and see if that works. Everything, so far, seems to be in sync. The phone would be right for a second when you went into the calendar and then change to be an hour off. Strange. I think the settings I have now (all, Windows, MobileMe, and the IPhone 3G set to DSL on, the same) may be working. Only time will tell.
Thank you.

How do you show only one caller's video output with four people sharing a video call? i.e. the call originator wants to show a DVD video on a TV screen and the other callers want to view the video on full screen not just one fourth of their screen.

The American Creed by William Tyler Paige
I believe in the United States of America as a government of the people, by the people, for the people; whose just powers are derived from the consent of the governed, a democracy in a republic, a sovereign Nation of many sovereign States; a perfect union, one and inseparable; established upon those principles of freedom, equality, justice and humanity for which American patriots sacrificed their lives and fortunes. I therefore believe it is my duty to my country to love it, to support its Constitution, to obey its laws, to respect its flag, and to defend it against all enemies.
