Utilizing Amazon Nova Professional for Video Evaluation
Nova Professional Interface
To exhibit video evaluation, I’ll enter one video into the enter :
Amazon Nova Professional can analyze movies which can be uploaded, I requested:
Whats occurring within the video?
Output:
In the beginning of the video, there are three cats on a ledge. One cat is grey and white, one is brown and white, and one is white. The white cat is on the appropriate facet of the ledge. The cats are trying in several instructions. There are some vegetation and timber within the background. Because the video progresses, the cats proceed to face on the ledge. The white cat strikes to the center of the ledge. The cats proceed to look in several instructions. The vegetation and timber within the background stay the identical.
Nova Professional API
I can use a extra detailed immediate to extract particular data from the video reminiscent of objects or textual content. Word that Amazon Nova at the moment doesn’t course of audio in a video.
I may use the AWS SDK for Python (Boto3) to invoke the Amazon Nova Professional mannequin utilizing the Amazon Bedrock Converse API and analyze the video. Please be sure that AWS is correctly configured in your system to make use of the API. Moreover, confirm that you’ve the mandatory permissions to execute the operations.
import boto3
AWS_REGION = "us-east-1"
MODEL_ID = "amazon.nova-pro-v1:0"
VIDEO_FILE = "/residence/abhishek/Downloads/cats_sample"
bedrock_runtime = boto3.shopper("bedrock-runtime", region_name=AWS_REGION)
with open(VIDEO_FILE, "rb") as f:
video = f.learn()
user_message = "Describe this video."
messages = [ { "role": "user", "content": [
{"video": {"format": "mp4", "source": {"bytes": video}}},
{"text": user_message}
] } ]
response = bedrock_runtime.converse(
modelId=MODEL_ID,
messages=messages,
inferenceConfig={"temperature": 0.0}
)
response_text = response["output"]["message"]["content"][0]["text"]
print(response_text)Amazon Nova Professional can analyze movies which can be uploaded with the API (as within the earlier code) or which can be saved in an Amazon Easy Storage Service (Amazon S3) bucket.
Output:
Utilizing Amazon Nova Reel for Video Creation
Now, let’s create a video utilizing Amazon Nova Reel, ranging from a text-only immediate after which offering a reference picture. As a result of producing a video takes a couple of minutes, the Amazon Bedrock API launched three new operations:
- StartAsyncInvoke: Initiates video creation.
- GetAsyncInvoke: Tracks the standing of creation.
- ListAsyncInvokes: Lists all ongoing or accomplished video duties.
Amazon Nova Reel helps digicam management actions reminiscent of zooming or transferring the digicam. This Python script creates a video from this textual content immediate:
A colourful flower backyard with roses, sunflowers,
tulips, and lavender swaying within the daylight.
The digicam zooms in to seize the
intricate particulars of every bloom..
After the primary invocation, the script periodically checks the standing till the creation of the video has been accomplished. I move a random seed to get a distinct outcome every time the code runs.
import random
import time
import boto3
AWS_REGION = "us-east-1"
MODEL_ID = "amazon.nova-reel-v1:0"
SLEEP_TIME = 30
S3_DESTINATION_BUCKET = "<BUCKET>"
video_prompt = "A colourful flower backyard with roses, sunflowers, tulips, and lavender swaying within the daylight. The digicam zooms in to seize the intricate particulars of every bloom."
bedrock_runtime = boto3.shopper("bedrock-runtime", region_name=AWS_REGION)
model_input = {
"taskType": "TEXT_VIDEO",
"textToVideoParams": {"textual content": video_prompt},
"videoGenerationConfig": {
"durationSeconds": 6,
"fps": 24,
"dimension": "1280x720",
"seed": random.randint(0, 2147483648)
}
}
invocation = bedrock_runtime.start_async_invoke(
modelId=MODEL_ID,
modelInput=model_input,
outputDataConfig={"s3OutputDataConfig": {"s3Uri": f"s3://{S3_DESTINATION_BUCKET}"}}
)
invocation_arn = invocation["invocationArn"]
s3_prefix = invocation_arn.break up("https://www.analyticsvidhya.com/")[-1]
s3_location = f"s3://{S3_DESTINATION_BUCKET}/{s3_prefix}"
print(f"nS3 URI: {s3_location}")
whereas True:
response = bedrock_runtime.get_async_invoke(
invocationArn=invocation_arn
)
standing = response["status"]
print(f"Standing: {standing}")
if standing != "InProgress":
break
time.sleep(SLEEP_TIME)
if standing == "Accomplished":
print(f"nVideo is prepared at {s3_location}/output.mp4")
else:
print(f"nVideo era standing: {standing}")Output:
After a couple of minutes, the script completes and prints the output Amazon Easy Storage Service (Amazon S3) location. I obtain the output video utilizing the AWS Command Line Interface (AWS CLI) or I can obtain it manually:
aws s3 cp s3://BUCKET/PREFIX/output.mp4 ./output-from-text.mp4
That is the ensuing video. As requested, the digicam zooms in on the topic.
Utilizing Amazon Nova Reel with a Reference Picture
To have higher management over the creation of the video, I can present Amazon Nova Reel a reference picture reminiscent of the next:
The supplied picture will need to have dimensions within the set [1280×720].
This script makes use of the reference picture and a textual content immediate with a digicam motion (drone view then a bee sitting on a flower when zoomed in) to create a video:
import base64
import random
import time
import boto3
S3_DESTINATION_BUCKET = "<BUCKET>"
AWS_REGION = "us-east-1"
MODEL_ID = "amazon.nova-reel-v1:0"
SLEEP_TIME = 30
input_image_path = "seascape.png"
video_prompt = "drone view then a bee sitting on a flower when zoomed in"
bedrock_runtime = boto3.shopper("bedrock-runtime", region_name=AWS_REGION)
# Load the enter picture as a Base64 string.
with open(input_image_path, "rb") as f:
input_image_bytes = f.learn()
input_image_base64 = base64.b64encode(input_image_bytes).decode("utf-8")
model_input = {
"taskType": "TEXT_VIDEO",
"textToVideoParams": {
"textual content": video_prompt,
"pictures": [{ "format": "png", "source": { "bytes": input_image_base64 } }]
},
"videoGenerationConfig": {
"durationSeconds": 6,
"fps": 24,
"dimension": "1280x720",
"seed": random.randint(0, 2147483648)
}
}
invocation = bedrock_runtime.start_async_invoke(
modelId=MODEL_ID,
modelInput=model_input,
outputDataConfig={"s3OutputDataConfig": {"s3Uri": f"s3://{S3_DESTINATION_BUCKET}"}}
)
invocation_arn = invocation["invocationArn"]
s3_prefix = invocation_arn.break up("https://www.analyticsvidhya.com/")[-1]
s3_location = f"s3://{S3_DESTINATION_BUCKET}/{s3_prefix}"
print(f"nS3 URI: {s3_location}")
whereas True:
response = bedrock_runtime.get_async_invoke(
invocationArn=invocation_arn
)
standing = response["status"]
print(f"Standing: {standing}")
if standing != "InProgress":
break
time.sleep(SLEEP_TIME)
if standing == "Accomplished":
print(f"nVideo is prepared at {s3_location}/output.mp4")
else:
print(f"nVideo era standing: {standing}")Output:
Once more, I obtain the output utilizing the AWS CLI:
aws s3 cp s3://BUCKET/PREFIX/output.mp4 ./output-from-image.mp4
That is the ensuing video. The digicam begins from the reference picture and strikes ahead.
